Deadline Proof helps you create tamper-evident documentation for deadlines, submissions, disputes, and compliance records. Log proof events with timestamps, timezone, notes, and stored attachments. Each entry is cryptographically linked into a hash chain so changes can be detected later. Export verification-ready reports when you need to share or preserve your record. Designed to be local-first, private, and permanent — no accounts, no subscriptions. 🔐 Core features • Create cases to organize important timelines • Log proof events with timestamps and timezone • Attach files and images (stored copies are hashed) • Tamper-evident hash chain linking all events • Search and pin important cases ⭐ Evidence Tools (one-time unlock) • Tamper-evident PDF reports with chain summary • Integrity verification to detect modifications • Evidence bundle export (PDF + JSON + stored attachments) • Secure backup and restore • Unlimited cases 🛡️ Privacy & control • Local-first storage (your data stays on your device) • No ads, no tracking • One-time purchase — unlock forever Use cases • Deadline and submission records • Refunds and disputes • Compliance documentation • Work, school, or personal proof tracking Important disclosure: Deadline Proof provides tamper-evident documentation based on device-recorded timestamps and stored attachment hashes.
